Specification of Letters Patent. Patentedy 20, 1918.

Application led October 2, 1916. Serial No. 123,317.

Be it known that I, ROBERT LUomN DEsrUJoLs, a citizen of the French Republic, residin at 26 route de Brie, J oinvillele- Pont, eine, France, have invented certain new and useful Improvements Relating to Condensers, of which the following is a specification.

This invention Vrelates to an. aero-condenser radiator for steam automobiles for the condensation of exhaust steam.

`The apparatus is essentially characterized by the provision oi' injection nozzles by means of which the exhaust steam to be condensed is mixed with the cooling water, the

vapor being at the same time utilized for producing the circulation within the radiator condenser.

Y The invention comprises the combination of elements for producing this result.

The invention is illustrated diagrammatically in the accompanying drawing. Figure l represents in vertical section an apparatus in the construction of which the invention is carried into effect. Fig. 2 is a side sectional elevation on the line 2 2 of Fig. 1.

As indicated in the drawing the aerocondenser radiatoris essentially constituted by the combination of an upper and a lower header connected by a battery of tubes forming the radiator condenser properly so called with an arrangement of injection nozzles. An outer casing provides a water jacket for the top, bottom and sides of the condenser proper leaving the front and back open to the atmosphere.

The cooling water is supplied from a reservoir conveniently arranged and passes into the lower end of the water jacket through the inlet orifice 1. The water liows in the direction indicated by the arrows and passes through the lateral passages 2 and thus arrives at the upper part of the apparatus where the nozzles 3 are mounted.y These nozzles 3 are disposed in the interior of a casing 4; which terminates at each side in converging diverging nozzles 5. The vapor to be condensed passes into the casing 4 through the inlet 10 and escapes by the nozzles 5 drawing with it the water which passes out through the nozzles 3. The vapor to be condensed and the cooling water are intimately mixed in passing the nozzles 5 and the mixture produced ii'ows into the upper part 6 of the condenser.

he upper part 6 of the condenser is connected to a bottom reservoir by means of a battery of tubes 7 in which circulates the mixture of water and vapor. The cooling .of the mixture is eilected in the battery of tubes under the action of currents of air which traverse the spaces 11 between the tubes. The water resulting from the condensation of the vapor mixed with the cooling water collects in the lower reservoir and passes out through the outlet 8 and thence to the water reservoir.

Y The filling of the water jacket is effected by the provision of an inlet at the upper end, which is closed by a cap 9.

It will be understood that the battery of i tubes may takethe form of smooth tubes as illustrated in the drawing or of tubes provided with ribs by which the radiatingsurface ma be increased, or it may take any other suitable form. For effecting the cooling and condensation the apparatus may' also be combined in known manner with a fan conveniently disposed behind the battery of tubes. Any desired number of nozzles may be employed.

The' invention is not limited to the construction represented in the drawing which may be varied according to the application of the invention and according to the kind of apparatus to which it is to be applied.

I claim:

1. A ,condenser for steam automobiles, comprisin an injector 'for the exhaust steam, a attery of air cooled condenser tubes into which the cooling water and exhaust steam from the injector pass, substantially as described.

2. A condenser for steam automobiles, comprising lateral passages on each side of the condenser, anl inlet for water at the lower end thereof, a header at the upper end of the condenser, an injector nozzle mounted in said header through which nozzle the cooling Water passes from the said lateral passages and a battery of tubes extending beneath the header in which the injector nozzle is mounted, and an outlet header into which the lower end of the tubes discharge, substantially as described.

3. A condenser for steam automobiles, a header Within which said injector is comprising an inject'or, said injector being mounted, a battery of tubes connecting the mounted inA the upper part of the radiator said headerwith abot'tom header into Which 10 and being yconstituted of a nozzle through' the condensedvaporl` and cooling -Water is 5 Which the cooling `Water passes and a surdischarged, substantially as described.
